SSP 7.1 • Introduction 1

SSP 7.1 Features

Advanced control and conﬁguration — The SSP 7.1 Setup and Control Software provides additional conﬁguration options beyond those available through front panel control.

Emulate and Live modes for conﬁguration — The control program can be used in

Emulate mode to create an SSP 7.1 conguration. The modications can be saved and

applied to the unit when a connection is established. In Live mode, the changes are made directly to the unit.

Four digital audio inputs — The unit accepts four digital inputs through two optical (TOSLINK®) digital inputs and two S/PDIF coaxial (RCA) digital inputs.

One analog input — The unit accepts one balanced/unbalanced analog input on a 5-pole

captive screw connector.

Conﬁgurable analog input — Input 5 accepts balanced or unbalanced stereo analog

inputs and can be conﬁgured to accept one or two balanced or unbalanced mono inputs through a captive screw connector. The mono source can be left, right, or a mix summed of the two.

Automatic surround sound format detection and decoding — The SSP 7.1

automatically detects the format of the incoming audio signal, and then applies the userdeﬁned decoding so that signals are sent to the appropriate outputs.

Input source surround sound format indicator — The appropriate LED indicator

illuminates to indicate the incoming format of the selected input source, whether Dolby Digital, DTS, PCM, or two-channel analog.

Dolby Digital and DTS playback — The unit is able to decode and process source format from Dolby Digital and DTS, in their originally encoded formats.

Matrix decoding — The surround sound processor can decode stereo signals to produce multichannel output.

Downmix multichannel source formats — Downmixing produces a mixed stereo or mono channel with an additional option to redistribute the downmixed signal to all channels.

Front panel audio level adjustment with LED level and analog clip indication — Provides overall output volume adjustment for all outputs as well as adjustment of input

level for the analog input. Accompanying LEDs display input gain level, and a dedicated LED

indicator illuminates red when analog clipping has occurred.

Multiple listening modes — Not all listening modes are compatible with certain input signals. The listening mode depends not only on the format of the source material but also on the speaker conﬁguration of the setting. Only those listening modes that are compatible

for a given input are available for that signal. The SSP 7.1 comes with factory default

listening modes that have been matched to the source format to take into account source format and speaker conﬁguration.

Listening mode override — Listening mode override customizes the listening mode to the needs of the source format, speaker conﬁguration, the venue, and the personal preferences

of the listener. Selections made through the front panel can be further rened by the SSP 7.1

Setup and Control Software.

This feature can be used to associate a speciﬁc listening mode with each input type, allowing the user to switch quickly to the listening mode that suits each input type for a given room conﬁguration and the individual user preferences.

SSP 7.1 • Introduction 2

Test signals for setup and calibration — The SSP 7.1 generates test signals, including

band-limited Dolby noise and full-bandwidth pink noise, to facilitate calibration of sound pressure levels from all speakers, and to ﬁne-tune the interaction of a speaker with the

acoustical environment. The SSP 7.1 also offers the option to use an external source for test

signals, which can then be directed to any speaker, or all speakers in sequence.

Speaker compensation delay — The signal to each output channel can be individually delayed so that the sound from all speakers is synchronized when it reaches the listener.

Lip sync offset — This feature delays an audio signal so that it is resynchronized with a video signal that has been delayed by video processing. The offset can be applied to each input channel independently.

Equalization — Nine bands of parametric EQ are available to enhance tone, compensate

for differences in individual speaker output, and adjust frequency response for a given acoustic environment.

SSP 7.1 • Features 4

NOTES: • The length of the exposed wires in the stripping process is critical. The

OUTPUTS

RS-232

ideal length is 3/16 inches (5 mm). Any longer and the exposed wires may

touch, causing a short circuit between them. Any shorter and the wires can be easily pulled out even if tightly fastened by the captive screws.

• Do not tin the wires. Tinned wire does not hold its shape and can become

loose over time.

For more information about input formats, see “Front Panel Features and

Operations” on page 6 and the “Source Formats” section on page 61.

Figure 3. Audio Outputs

Individual output settings are configured through the SSP 7.1 Setup and Control

Software (see page 30) or SIS commands (see page 86):

Mono — Output is through the center channel only but can be reconfigured to be

output through the left and right front channels. In the absence of a center channel, mono is also output through the left and right front channels.

2-channel (stereo) — Only the front left and front right channels are used.

2.0 to 2.1 surround configurations — Audio is output through front left and front

right channels with (2.1) or without (2.0) a subwoofer.

3.0 to 3.1 surround configurations — Audio is output through front left, front right,

and center channels with (3.1) or without (3.0) a subwoofer.

4.0 to 5.1 surround configurations — Audio is output through a combination of front left and right, left and right surround, center and subwoofer channels.

6.0 to 6.1 surround configurations — Adds a back channel to 5.0 or 5.1

configurations. The back left channel receives the sixth channel information and serves as the center back speaker in this configuration.

7.0 to 7.1 surround configurations — Both the back left and right channels are active. Listening modes designed for 6.1 channel outputs pass the same signal to both the back left and right channels. Listening modes designed for 7.1 channel outputs pass

separate signals to each channel to produce a stereo back sound effect.

For more information about speaker configuration and output formats, see the

“Listening Mode Options and Usage” section on page 66.

d RS-232 port — The SSP 7.1 can be congured using the SSP 7.1 Setup and Control

Software or SIS commands, using this 3-pole captive screw connector (or the 2.5 mm

Tip Ring Sleeve (TRS) mini jack plug on the front panel). For more information about the SSP 7.1 Setup and Control Software, see

Source Format

f Input source format indicator — The bank of four LEDs identify the format of the

audio input.

z Dolby Digital ( D): Dolby Digital 2/0, Dolby Digital 2/0 Surround, Dolby Digital 5.1,

or Dolby Digital Surround EX.

z DTS: DTS 2-Channel, DTS Digital Surround, DTS 96/24, DTS-ES Matrix 6.1,

DTS 96/24 ES Matrix 6.1, or DTS-ES Discrete 6.1.

z PCM: 2-channel uncompressed digital source format.

NOTES: • A digital signal that does not have a supported sampling rate or is

compressed PCM is considered an unrecognized signal and is muted.

• When a DVD player is paused during playback, the SSP 7.1 may or

may not continue to receive source format information from the

DVD player. Some players continue to send the same source format information in a loop, allowing the SSP 7.1 to retain the previous settings. Other DVD players completely disconnect the signal from the SSP 7.1 (unlocked state), so that the active input blinks as if there is no connection present. The remainder of DVD players change the source

output to PCM without an actual signal being sent (digital silence).

During digital silence, the PCM LED lights but the 2-CH source LED

does not.

z 2-Channel (2-CH):

z Any source coming through analog input 5.

z If a PCM digital signal is present on any of the digital inputs, both the PCM and

the 2-CH LEDs light.

z If a Dolby Digital 2/0 or Dolby Digital 2/0 Surround source is present, both the

D and the 2-CH LEDs light.

z If a DTS 2-Channel source format is present, both the DTS and 2-CH LEDs light.

To understand more about source formats, see page 61.

SSP 7.1 • Features 6

Mode Override Selection

MODE OVERRIDE

g Mode Override selector — The SSP 7.1 has a wide range of listening modes,

although not all listening modes are compatible with every source format. The speaker conﬁguration of the system may further limit which listening mode is available for a source format. Other factors, such as the room layout and listener preferences, may also inﬂuence the listening mode selection.

The SSP 7.1 has default listening modes associated with each source format. The front

panel provides the user with a limited set of Mode Override settings. These can change the listening mode that is associated with a specific combination of source format

and input. The override selections can be further defined using the SSP 7.1 Setup and

Control Software, or SIS commands.

The new, user-defined listening mode continues to be associated with that source format until Mode Override is used, again, to associate a new listening mode with the source format. To select a listening mode:

1. Use the push button to toggle through the available listening

modes. When no mode override is chosen, none of the LEDs

light, indicating that a user-deﬁned listening mode is in use.

Otherwise, one of the four LEDs shows the current selection.

2. Release the button when the desired LED is lit to select that

listening mode. If a listening mode is not an available option for the current input source, toggling the button skips that mode and goes to the next available mode.

3. If required, further dene the selection using the SSP 7.1 Setup and Control Software

The mode override selections that are available through the front panel are:

z Downmix (DOWNMIX) — Downmixes any multichannel source format (digital

inputs only). It also downmixes a 2-channel source format, if the listening mode is set to mono.

It is further defined from the Setup and Control Software (see page 48). Options include:

z Stereo, output on left front and right front channels.

z Mono, output to center channel only or to left and right front channels equally.

z Dolby Pro Logic II/IIx ( PL II/IIx) — uses Dolby Pro Logic II or Dolby Pro Logic IIx

surround processing technology.

z Dolby Pro Logic II extends 2-channel sources to output 5.1 channels. It can be

further deﬁned by control software as either Dolby Pro Logic II Movie (default) or Dolby Pro Logic II Music.

z Dolby Pro Logic IIx extends 2-channel sources to output 6.0 to 7.1 channels

(depending on the speaker setup). It can be further deﬁned by control software as either Dolby Pro Logic IIx Movie or Dolby Pro Logic IIx Music.

z Dolby Pro Logic IIx also provides an extended surround option for multichannel

sources such as DTS Digital Surround or Dolby Digital 5.1.

z DTS Neo:6 (DTS NEO:6) — Uses DTS Neo:6 surround processing technology

to extend analog or 2-channel digital source formats (PCM, Dolby Digital 2/0,

Dolby Digital 2/0 Surround, DTS 2-Channel) to output up to 7.1 channels. It

is further deﬁned by control software as either DTS Neo:6 Cinema (default) or DTS Neo:6 Music.

The input buttons are also used to enable or disable front panel security lockout

(executive mode). For more information, see page 12. In conjunction with the volume adjust knob, the analog input (Input 5) is used to set

analog input gain level for the analog source (see page 11).

The SSP 7.1 accepts four digital inputs and one analog input (see Rear Panel Features on page 4):

z Inputs 1 and 2 accept digital signals through S/PDIF optical cables. The optical

cable supports TOSLINK or TOSLINK-compatible optical connectors that conform to

IEC-958, S/PDIF standards.

z Inputs 3 and 4 accept digital signals through S/PDIF coaxial cables.

All four digital inputs accept 16-24 bits PCM audio at 32, 44.1, 48, 88.2, and 96 kHz

sample rates. They support Dolby Digital and DTS source formats.

NOTE: For digital inputs, if there is no valid clock signal at the input and no lock is

achieved, the LED associated with the source blinks twice per second.

z Input 5 accepts a balanced or unbalanced analog input through a 5-pin captive

screw connector. The unit can be conﬁgured to accept:

z A stereo signal

z A mono signal from the right channel

z A mono signal from the left channel

z A mixed sum of right and left channels

The input can also be selected using the SSP 7.1 Setup and Control Software (see Input

SSP 7.1 • Features 9

Mute Output

When the mute state is enabled, all channels are muted simultaneously. To toggle between

mute and unmute:

1. Press and hold the active input button (the button next to the LED that is lit).

2. While still holding the active input button, press the Mode Override button.

When the mute state is enabled, the individual LEDs of the Volume Adjustment LED bar light

in sequence from the top down. This scrolling down pattern repeats while the mute state persists.

All channels can also be muted using the SSP 7.1 Setup and Control Software (see Master

Volume and Mute on page 29).

NOTES: • Selecting another input button while the mute function is enabled, disables

the mute function.

• Adjusting the volume control encoder to change the volume (or the analog

input gain) settings while the mute function is enabled, disables the mute function and increases (or decreases) the volume (or gain) from its previous setting.

• If SIS commands have been used to mute a specific channel, muting and

unmuting all channels also unmutes the channel that was specifically muted. It does not remain in its previously muted state.

Complete System Reset

The SSP 7.1 has three levels of System Reset.

Standard system reset — All parameters that can be adjusted by the control program are reset to default.

Factory reset — In addition to resetting all the parameters of the standard system reset, the baud rate for communicating with the computer is also reset.

Complete system reset — In addition to resetting all the parameters of the factory reset, the ﬁrmware is reset to the factory-installed version.

The standard and factory resets are performed using SIS commands (see the System Reset

SIS commands on page 94).

To perform a complete system reset, hold the Mode Override button while shutting off and restoring power.

Alternatively, the rotary encoder controls the gain level

of the analog signal on input 5. Analog input gain is adjustable from 0 dB (fully counterclockwise) to +24 dB

(fully clockwise).

To adjust input gain, press and hold the Input 5 button,

while turning the rotary encoder.

CLIP

NOTES: • If the gain level is too high, clipping may occur. When clipping occurs, the red

LED above the Input 5 button lights.

• When using Mono or Mono to All listening mode, the left and right signals

are summed (in the digital domain), which can cause a boost in level up to

6 dB. This type of clipping does not cause the clip indicator LED to light but

is audible. If using a mono mode, it is recommended that the input gain be

reduced by 9 dB below clipping to prevent clipping from occurring.

SSP 7.1 • Features 11

The LED bar lights from the bottom up to indicate the current gain level. No LEDs lit indicates no gain (0 dB, or unity gain); all the LEDs lit indicates maximum gain (24 dB).

Figure 9. Subwoofer Placement

NOTES: • To produce a good bass response from the subwoofer, it should be located at

the front of the room, somewhere between either corner and a point about one third of the way along the front wall.

• The output channel used for the Left Back speaker (in 7.1 configurations) is

also used for the Center Back speaker (in 6.1 configurations).

Bass Management

Speaker Size Settings

Low frequency sound is usually better handled by the subwoofer. Bass management creates the subwoofer channel by separating the low frequency information from the satellite

speakers at a user-dened crossover point. This is summed with the Low Frequency Effects (LFE) information encoded in the source format. When no subwoofer is present, subwoofer

content is sent to speakers set to Large (excluding the center speaker).

This feature sets bass management on or off for a particular speaker, deﬁning the frequency range output by that speaker. These settings also enable or disable the subwoofer and set the crossover frequency.

z Left and right front speakers and left and right surround speakers are set in pairs.

z The center speaker is set as an individual speaker. z Back speaker(s) can be set as a single speaker or as a pair of speakers, depending on the

system conﬁguration.

Small — Bass management is on for that speaker. The output to each speaker (other than the subwoofer) is limited to frequencies above the crossover frequency. By default, center

and surround speakers are set to Small.

SSP 7.1 • Setup 15

Large — Bass management is off for that speaker. The full range of audio frequencies from

the audio source is fed through the output of each individual channel. This may be set in the

absence of a subwoofer. By default, front speakers are set to large. When there is no subwoofer, all speakers set to Large (except the center channel) receive the

summed audio from the ﬁltered low frequency signals of speakers set to Small.

None — This mode prevents any signal from being sent to that output channel. It is not an option for front speakers.

One Small Speaker, Two Small Speakers, One Large Speaker, Two Large Speakers, or None (Surround back speakers only) — This mode determines whether the audio output

channels for the back speaker(s) are passed to the left back and right back (in 7.1 setups) or to the center back (in 6.1 setups).

If either of the one speaker options are chosen, the highest possible number of outputs is

6.1 speakers. In this case, the output is directed to the left back channel output. If either of the two speaker options are chosen, the SSP 7.1 is able to output up to 7.1

channels. Source formats with discrete or matrix mixed 6.1 encoded channels output the

surround back channel signal equally to the left and right back channels. Dolby Pro Logic IIx and DTS Neo:6 listening mode options output a stereo signal to the left and right back channels.

NOTE: If the surround speakers have been disabled, the back speaker options are also

disabled.

By default, the back speaker is set to None, which prevents a signal from being output on

the back channel(s).

Subwoofer — This option allows the subwoofer to be enabled or disabled. When the

subwoofer is enabled, the signal contains ﬁltered low frequency signals from speakers set

to Small in addition to the LFE signal from the source format. If the subwoofer is absent or disabled, the LFE signal is mixed with the bass information of all speakers in the system that

are set to Large, except the center speaker.

NOTES: • When the surround and back speakers are set to None, all multichannel input

signal formats are downmixed and output on all remaining channels.

• In addition, in the absence of a center channel, mono signals are output

equally between the front left and front right channels. Multichannel sources are downmixed to all remaining channels, but Mono to All and Stereo to All options are disabled. Choosing Mono listening mode first downmixes the multichannel source and outputs it to the front left and right channels equally as a dual mono signal.

Crossover Frequency — The crossover frequency sets the boundary below which the low frequency signals from designated output channels are incorporated into bass management. Low frequency signals are only taken from speakers that have been set to Small (see ”Speaker Size Settings” on page 15). The bass management signal is passed to the subwoofer (if present) or speakers that have been set to Large (except for the center speakers) if a subwoofer is not present.

The crossover frequency can be adjusted within the range of 40 Hz to 250 Hz, with a default setting of 100 Hz. Speakers set to Small (see “Speaker Size Settings” on page 15) play

only signals above the set frequency.

SSP 7.1 • Setup 16

Speaker Delay Settings

There are two different signal delays that compensate for different needs.

Compensation delay — In a room where speakers are not equidistant from the listener, sound from the closest speaker reaches the listener before sound from the farthest speaker. This feature allows the user to enter the speaker distance value for each speaker output

channel. The application calculates the delay values for the closest speakers, up to 100.0 ms,

so that all audio arrives at a central location (the “sweet spot”) at the same time.

Lip sync offset — Video delays occur due to changes in programming from a source (TV, Cable, Satellite, or DVD player) and also if the video signal has to be processed through

another device between the source and the display. The lip sync offset feature allows the user to delay the audio sent to all output channels so that video and audio output are synchronized.

Since each source may need a different level of compensation, the lip sync offset for each

input is independently adjustable from 0.0 to 100.0 ms. Apply lip sync offset to the audio

until what is heard matches up with what is seen on the display.

To congure these settings using the SSP 7.1 Setup and Control Software, see “Speaker

Delay Tab” on page 32.

Test Signals

Test signals are used during setup to calibrate the level for each channel and to ensure

proper connection between the individual output channels of the SSP 7.1 and the line

level input channels of an audio signal processor, a receiver with built in ampliﬁer, or a stand alone ampliﬁer that powers the loudspeakers.

The three options for test signal source are pink noise, Dolby noise, and an external source.

By default, the test signal is switched off. Pink Noise — Pink noise is a random signal, generated by the SSP 7.1, with all audio

frequencies present. It provides equal energy per octave to provide a ﬂat response over all frequencies. The main purpose of pink noise is to calibrate the interaction of a speaker with its environment.

Dolby Noise — Dolby noise provides a bandpass-ltered noise, centered at 750 Hz with a 12 dB/octave roll off. This signal is also generated by the SSP 7.1 and is used to set speakers

to the same level when calibrating the room.

Active Input — This option requires an external test signal source, such as a signal

generator, played through the selected input source. Generally, this is a device with an analog signal output, with the SSP 7.1 analog input used as the active input.

Signal generators are usually used to test specic decoding mode outputs. When the External Source option is chosen, the speakers that receive the test signal can be specied.

To calibrate speaker output, use any of these test signals with the SSP 7.1 Setup and Control

Software, see Test Signals on page 36.

Output Channel Trim Settings

This control adjusts the output channel trim level for each output channel to match the levels to the unique needs of any listening environment. The level can be adjusted within the

range from -24 dB to +12 dB. The default setting for each speaker is 0 dB. See Output Trim

on page 39 for more information.

SSP 7.1 • Setup 17

Listening Mode Settings

The SSP 7.1 provides a range of settings that rene the sound distribution for each listening

mode, depending on the decoding mode that has been selected.

Dolby Pro Logic II or IIx Music

Dimension control — This feature alters the ratio of L+R to L-R for two-channel input

signals, which adjusts the sound ﬁeld towards the front or towards the back. The available

settings are Front, Neutral, or Back. The default setting is Neutral.

Center width control — Pro Logic decoding produces a single center signal that comes from the center speaker. If there is no center speaker, a “phantom” center image is produced that is split between the right and left speakers.

If right, left, and center speakers are present, center width control allows variable adjustment of the center image so that is heard only from the center speaker, only from the right and left speakers, or from all three speakers in varying degrees.

There are up to eight different settings, with each corresponding to a speciﬁc calculation angle (Φ). When the setting is 0, the sound comes from the center speaker, when the setting is 7, the sound is from the L/R speakers. The default setting is 3.

Control Position Calculation Angle

0 0.0 0.0 Off 1 20.8 -0.6 -12.0 2 28.0 -1.1 -9.6 3 36.0 -1.8 -7.6 4 54.0 -4.6 -4.8 5 62.0 -6.6 -4.1

6 69.2 -9.0 -3.6

7 90.0 Off -3.0

NOTE: The level of the center speaker (C Level) is related to cosine Φ. The level of the

left and right speakers (L/R Level) is related to sine Φ.

Panorama control — This feature extends the center width control, so that all or part of the center image can be heard from the surround speakers for a “wraparound” effect. The feature may be On or Off. The default setting is Off.

C Level (dB) L/R Level (dB)

DTS Neo:6 Music or Cinema

Center image control — The center image control varies the amount of attenuation applied to the left and right channel information of the input source that is used for creating

the output center channel effects. When it is set to 0, the mixed input signal information,

intended for use in creating the center output channel of the DTS Neo:6 listening modes, is ﬁltered back to the front left and right output channels. This creates the effect of spreading

the centralized audio signal across all three front output channels. When this control is set to 10, the matrixed information intended for the center output channel effects is fully

attenuated, allowing the center channel to create a more centralized effect from the front channels.

The default setting for DTS Neo6: Music is 3. The default for DTS Neo6: Cinema is 10.

SSP 7.1 • Setup 18

Dynamic Range Compression Control

This control is available only with Dolby Digital and DTS source formats that have a Dynamic Range Compression ﬂag.

This control adjusts the gain applied to Dolby Digital or DTS listening modes to compress the signal outputs during the decoding process. The three possible settings are None, Minimum, and Maximum. The default setting is None.

Off — The signal is uncompressed and is played with the full original dynamic range.

Minimum — The audio is partially compressed. In this mode, the volume of the loudest

passages is reduced but quieter passages are kept at their original level. This level is recommended for normal listening.

Maximum — The audio is fully compressed. This level is recommended for environments where loud audio is not permitted.

NOTE: DTS source formats have only two states (On and Off) for dynamic range

compression. Therefore, Minimum and Maximum both apply the same dynamic range compression.

SSP 7.1 • Setup 19

Tone Controls

These controls regulate the bass and treble settings for the system. To adjust the bass or treble tone controls, see Tone Controls on page 27.

Bass — The bass control regulates the amount by which low frequency signals are boosted or cut (see ﬁgure below). It is applied to outputs for all speakers, including the subwoofer.

Figure 10. Bass Range

Treble — The treble control regulates the amount by which high frequency signals for all speakers, except the subwoofer, are boosted or cut (see ﬁgure below).

Figure 11. Treble Range

SSP 7.1 • Setup 20

Volume Output

Equalization

This control sets the volume of the audio output through all channels, globally, to either

Variable (the default value) or Fixed. Variable — When the Volume output is set to Variable, the volume can be attenuated using

the front panel knob, the SSP 7.1 Setup and Control Software, or SIS commands.

Fixed — The Fixed option sets the volume to the current attenuation level. Likewise, all the Output Channel Trim levels (see Output Trim on page 39) are ﬁxed at the values they had

immediately before the Volume Output was set to Fixed. When Fixed is selected, the volume cannot be adjusted through the front panel knob, by the

SSP 7.1 Setup and Control Software, or by SIS commands.

Parametric equalization (or parametric “EQ”) allows the control of amplitude of each band,

center frequency (which can be shifted, widened, or narrowed) and bandwidth (which may

be labeled “Q” for Quality). Parametric equalization is used to improve the audio output in a

speciﬁc acoustic environment.

Resonance reduction — Reduces the level at speciﬁc frequencies that are too loud.

Speaker compensation — Compensates for peaks and dips in individual speaker output

response.

Tonal enhancement — Increases the level of frequencies within a broad or narrow range that sound too quiet.
